Following your prostate biopsy, a urologist will send that tissue to a pathologist who
will look at it under a microscope. The pathologist will then generate a Gleason score. The Gleason
score is based upon a scoring system looking at the cells and giving them a score ranging
from one to five. One are very well-differentiated slow-growing cells, while five are very poorly-differentiated,
fast growing regressive. Pathologists will look at the two dominant areas of cancer on
a slide and give a summary of those two scores, known at the Gleason score. The Gleason score
will typically range from five to ten. Five is slow-growing, well-differentiated, less
aggressive, and ten is fast-growing, poorly differentiated and very aggressive
